Damping force test of washing machine suspension rod

Introduction to testing machine:

Suspension rod damping force life testing machineGenerally used for damping mechanical analysis and testing of suspension rods in washing machines. At a certain temperature, conduct a certain running in life test and then test at a certain speed. The testing height of the suspension rod varies depending on the type. It is a load displacement test of a fixed stroke at a certain height. At the same time, life testing can be conducted, and additional workstations can be added for testing according to customer requirements.

Definition of damping force:

damping（Damping refers to the physical phenomenon in which energy is dissipated over time due to the obstruction of a shaking or vibrating system

The function of damping:

Damping helps to reduce the resonance amplitude of mechanical structures, thereby avoiding structural damage caused by dynamic stress reaching its limit.

Damping helps mechanical systems quickly recover to a stable state after being subjected to instantaneous impacts.

Damping helps reduce sound radiation caused by mechanical vibrations and lower mechanical noise.Many mechanical components, such as the shells and saw blades of transportation vehicles, produce noise mainly caused by vibration. Damping can effectively suppress resonance and reduce noise.

Damping force detection:

Suspension rod damping force testing machineThe function is that in our daily lives, common damping phenomena are reflected in damping forces such as shock absorbers and suspension rods. And both of these products are designed for high-frequency and high lifespan use. For example, the suspension rod of a washing machine,The outer convex spherical surface of the suspension rod spring sleeve is matched with the corresponding inner concave spherical surface on the outer barrel, so as to hang a complete set of transmission components such as the outer barrel, inner barrel, motor, clutch, etc. on the outer barrel. When vibration occurs during the washing or dehydration process, the spring sleeve swings along the spherical surface and slides up and down along the suspension rod to absorb vibration energy, thereby reducing the vibration noise of the box and keeping the whole machine stable.
